DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container supporting device for preventing a container stacked on a hatch cover of a container ship having a hatch cover from shifting laterally.

[0002]

2. Description of the Related Art FIG. 11 is a perspective view showing the inside of a hold of a container ship. The container ship a that transports the container e normally stacks the container e on the hatch cover d that closes the inside of the hold b and the opening f of the deck. The hold b has a cell guide c for guiding the loading of the container e and preventing the loaded container e from laterally shifting. Conventionally, since there is no cell guide on the hatch cover d, the container e is fixed by a lashing hardware having a turnbuckle (not shown), and the upper and lower connecting hardware is used by using holes (not shown) at four corners of the upper and lower surfaces of the container e. By connecting the upper and lower containers e, the lateral displacement of the container is prevented.

[0003]

However, lashing by lashing hardware requires a heavy turnbuckle to be manually carried and mounted and rotated, which poses a safety problem. Furthermore, since the connection of the upper and lower containers by the upper and lower connection hardware is used at the four corners of all the containers,
Since the number of installations is large, and the work is performed at narrow places and at high places, there is a problem that the efficiency of container handling work is reduced.

The present invention has been made in order to solve the above-mentioned problems of the prior art. By mounting a movable frame provided with a foldable container guide on a hatch cover, It is an object of the present invention to provide a container support device that prevents lateral displacement of a container during navigation, eliminates the need for securing work with lashing hardware, etc., facilitates the loading and unloading of containers, and improves the efficiency of cargo handling. Is what you do.

[0005]

A plurality of upper corner fittings having holes are provided.

According to another preferred embodiment of the present invention,
The fixing device has a plurality of pins that fit into connection holes provided separately from hinges at lower end portions of respective guide hardware and upper end portions of brackets supporting the guide hardware. The pin is provided on a long shaft disposed so as to penetrate, and the pins are simultaneously fitted into the connection holes by sliding the long shaft by a cylinder in the longitudinal direction.

Next, the operation of the present invention will be described. When the storage of the container in the hold is completed, the hatch cover is put on the mouth of the hold. On this hatch cover, a frame body having guide hardware temporarily placed on the ground or the like is suspended and transported by a spreader of a container crane, and placed, and the upper surface of the hatch cover and the lower surface of the frame body are fastened with a fastener. Fix it. Next, remove the spreader from the frame, lift the upper end of the guide hardware folded into the frame by the spreader, raise each guide hardware, operate the cylinder, slide the long axis, and connect each pin to the connection hole. Fit and fix all at once.
After the guide hardware is erected in this way, the container is transported by a container crane, suspended while being guided by the guide hardware, and stored on the frame. When the storage of the container on the frame is completed, the four corners on the lower side surface of the uppermost container are fixed by a tightening device provided at the upper end of the guide hardware. Since the container is restrained at the four corners by the guide hardware and is fixed by a tightening device above the guide hardware, there is no occurrence of lateral displacement or lifting. on the other hand,
When removing a container from the hold, the guide hardware is folded, the frame is moved to the ground by a container crane, the hatch cover is removed, and the container is removed from the hold.
